Portrait of Dr. Cynthia Lum
Assistant Professor
George Mason University

Dr. Cynthia Lum is the Deputy Director and Assistant Professor of the Center for Evidence-Based Crime Policy in the Department of Criminology, Law and Society at George Mason University. She conducts research primarily in the area of policing. Her works in this area have included evaluations of policing interventions for crime prevention effectiveness, examining place-based determinants of street-level police decision-making, understanding counterterrorism efforts by state and local law enforcement, and examining the relationship between drugs and violence using large policing datasets. With Christopher Koper (Police Executive Research Forum) and Cody Telep (Mason), Dr. Lum has developed the Evidence-Based Policing Matrix, a translation tool designed for police practitioners to better institutionalize and utilize research on "what works" in policing into their strategic and tactical portfolio. She recently completed a randomized controlled experiment in evaluating license-plate recognition technologies.
